I've loaded it and played with it. Works fine, but I've got to get my IM dept to activate my PIN and IMEI tomorrow for full capability. Instal was a breeze.
It works fine on my E61. Email sync and calendar is fast. However, I am trying to resolve PIN messaging issues. Right now, if someone sends a pin to me, it is shown as delivered, but nothing actually arrives. Maybe that's why they removed it.
